5 Claims.

This invention relates to butter molds such as are used in creameries. The object of the invention is to provide new and useful improvements in a butter mold to be used in a Creamery wherev5 by the butter may be quickly and easily released and removed from the mold in a perfect shape, and in a sanitary condition.

or When empty or full of butter,

aged by dropping.

A further object is to provide a mold which is perfectly smooth on the inside, and which will not damage the-butter wrapper when the butter is being removed from the mold.

n A further object of the invention is to provide a mold which produces a .cake of butter With parallel sides which may be cut into the conventional size pound packages with no waste, and

also be easily released from the mold.

A feature of the mold is that it can easily be kept in a perfectly sanitary condition due to having all its parts open and exposed to any cleaning or sterilizing agent.

Another feature of the invention is that it is simple having very few parts, and it can be easily and cheaply manufactured.

These objects of the invention are hereinafter more fully described and claimed, and the preferred form of construction and `association of the parts involving my invention is shown in the drawings in which- Corner.

Fig. 5 is a fragmentary view of the underside of the top flange at an open corner.

Fig. 6 is a fragmentary elevation of either of the open corners.

Fig. 7 is an elevation view of the lever. Fig. 8 is a vertical view of the lever.

Fig. 9 is an elevation view of the lever and connecting link.

Fig. 10 is a fragmentary cross section of an open corner and the operating lever and link.

Fig. 11 is a perspective view of the mold.

Fig. 12 is a plan view of the sheet of material from which two sides and the triangular flange is formed.

Fig. 13 is a fragmentary perspective view of the under side of the top flange at an open corner.

Fig. 14 is a perspective View of the inside of two sides and a fragmentary view of the bottom.

Referring to the drawings, in which for the sake of illustration is shown the preferred em* bodirnent of the invention, the numeral I2 designates the bottom of the mold preferably in the, form of a square to Which at its edges the sides I3 and I4, I5 and I6 are secured by common means such as welding. The sides I5 and I6 and the triangular flange 2l are all formed from a flat sheet of metal, see Fig. 12, also the flanges I'I are formed from the same sheet of metal. A out is made at the point C approximately to a depth of twice the width of the flange I'I and a cut is made also at F. The sheet is then folded along the dotted line D, and then broken to a right angle along the dotted line E, forming flange I'I. `The sheet is again broken to a right angle along the line I8-I8, with the flanges I'I outermost. The sheet is again broken along the dotted line G to a little greater angle than a right angle thus forming the triangular ange 2l. It will also be observed that the notch 23,

'see Figs. 12 and 13, is cut in the sheet before the sheet is first folded. The opposite sides I 3 and I4 and the flanges I'I and 2I are formed in identically the same manner.

At the corners I8' small square plates I8 are Welded to the ends of the flanges Il thereby forming a rigid corner. The bottom plate I2 is welded at its edges to the bottom edges of the sides I3, I4, I5, and IG as at W, in Figs. 11 and 14, thus forming a rectangular box with vertical sides.

At the end 22 of the flange Il an angular notch 23 better shown in Figs. 4, 5 and 13, is out in the lower fold of the metal forming the flange I1. Referring to Figs. 4, 6 and 13 it will be readily observed that the top edge of the triangular flange 2I when in position slides under the ange I'I at its end 22, and also between` the side Wall and the notched edge 23 of the flange Il, this notched edge of the flange has a two purpose: first, it forms a retaining guide for the top of the flange section 2l which holds the sides I3 and I5 tight and in place when the mold is closed; second, it will be observed that the ange 2| is broken to an obtuse angle from the side I6, see Fig. 4 and that the notch 23 is cut in the flange I'I so that the wide part of the notch is furthermost from the end 22. Thus it will be observed that as the mold is opened, the flanges 2| when working against the angular notches 23 will move the sides I3 and I5 slightly outward and helps to loosen the sides of the mold from the butter.

The numeral 24 designates a lever which is provided with the handle 25 at one end and with the hole 26 in the other end also with the hole 2 positioned close to the hole 26, and it will be noted that the center of the hole 2I is above a line drawn through the center of the hole 26 and the center of the handle 25. The lever is also provided with the stop 28 which is in the form of a small ear turned at a right angle to the lever body.

The numeral 29 designates a connecting link which is provided with the holes 30 and 3| in opposite ends, said link having an offset 32 in the form of a semicircle and approximately in its center. By inserting a rivet 2I through the hole 2'I in the lever 24 and through the hole 30 on the connecting link 29 and upsetting the ends oi the same, Fig. 10, a hinge joint is formed between the lever 24 and. the link 29. By inserting the rivet 26 through the hole 3U' in the side I3 and through the hole 26 of the lever 24 and upsetting the ends of the same: a pivotal connection is formed and upon which the lever 24 pivots. By inserting a rivet 3| through the hole 3|" in the ange 2| and through the hole 3| in the connecting link 29 and upsetting the ends of the rivet, a bearing connection is made between the flange 2| and the link 29, thus forming an operable mechanism to open and close the movable corner. A like lever and connecting link are secured in like manner to the side I and the flange 2| at the opposite corner of the mold. Referring to Fig. 2, the mold is shown with a corner open, and it will be observed that the handle 25 of the lever 24 is up in the curved portion 32 of the link 29 and that the lever 24 pivots on the rivet 26 through the hole 26, and also that when the lever 24 is .in the position above described, that the rivet 21' which passes through the holes 2'I and 30 in the lever and the link respectively is above the rivet 26 in the end of the lever 24 which causes the lever to be locked in position to hold the corner of the mold open. The action is identical on the opposite corner of the mold.

By depressing the handle 25 of the lever and swinging it down and around the pivot rivet coacting with the hole 26 of the lever, the lever is brought up in approximately a horizontal position and is stopped by the ear 28 contacting the top of the link 29. During this operation the corner formed by the side I6 and the flange 2| is moved toward the edge I9 of the side I3, better shown in Fig, 10, until the two sides are together and form a tight corner when such sides are locked by the lever 24 and the link 29. This action is also identical on the opposite corner.

The bottom piece I2 is provided with the hole 33, the purpose of which is to admit air to enter the bottom of the mold as the butter is released. It will be observed that when the corners of the mold are opened there will be a bending action set up in the bottom of the mold which is along the dotted line B-B, which action helps very materially in releasing the butter from the bottom of the mold. To the sides I3 and I5 are attached by common means the handles 34 and 35 which are used in handling the mold, said handles fold against the sides when not in use. It is clearly shown in Fig. 2, that the edge 36 of the flange 2| can never be moved out past the edge I9 of the side I3 by means of the operating lever 24 and the connecting link 29, and the same is true of the opposite corner. This insures a positive closing of the corner when the lever 24 is operated to close the corner, due to the fact that the edge 36 of the flange 2| can never come in contact with the edge I9 of the side I3, and the same is true of the opposite corner.

From the above description it will be readily observed that the device will mold a product with horizontal sides and release the same without marring the corners or sides, that it is strong and rigid and can be easily kept in a perfectly sanitary condition.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is 1. A butter mold having a bottom with four sides attached thereto thereby forming a rectangular parallelogram, the top of each side terminating in an outward flange, two opposite corners of the mold being rigid and two opposite corners being non-rigid, each of the non-rigid corners having a triangular shaped flange inclined at an angle to one of the sides and being a continuation of said side, the base of said triangular iange being uppermost, angular notches cut on the underside of the rst named flanges at their end at the non-rigid corners, the top of said triangular anges being held between the sides of the mold and the notches cut in the flanges, means for movably connecting the triangular flanges to the adjacent sides of the mold, and a hole in the bottom of the mold.

2. A mold of the character described having a bottom and four sides attached thereto, the top of each side having a flange at an angle to and on the outside of the mold, with two corners rigid and two corners movable, one side at each of the movable corners having a flange at an angle thereto, means for movably connecting the said flanges to the adjacent sides of the mold, and means for holding the top of the second said flange in operable position with the first said ange.

3. A butter mold of the character described having a bottom and four sides attached thereto, with two opposite corners rigid and two opposite corners movable, one side at each of the movable corners having a ange at an angle thereto, means for movably connecting the flanges to the adjacent sides of the mold, an operating lever attached to each of said adjacent sides of the mold, and means for connecting said operating levers to said flanges, said movable corners being locked in either open or closed position by means of an operating lever.

4. A butter mold of the character described having a bottom and four sides attached thereto, the top of each side having a flange at an angle to and on the outside of the mold, with two corners rigid and two corners movable, one side at each of the movable corners having a flange at an angle thereto, means for movably connecting the said flanges to the adjacent sides of the-mold,

tached to one side of the mold close to each of the movable corners, and means for connecting the operating levers to the adjacent sides of the mold `at the movable corners, said movable corners being locked in either open or closed 5 position by means of an operating lever.
